    ARM: mach-shmobile: sh7372 A3SM support · cf33835c

    This patch adds sh7372 A3SM power domain support.
    
    The sh7372 A3SM hardware power domain contains the
    ARM Cortex-A8 CPU Core including L2 cache. This
    sleep mode can be seen as a one step deeper sleep
    mode from the already existing Core Standby mode.
    
    To wake up from A3SM sleep only a few wakeup sources
    are supported - so the regular INTC controller will
    not be able to help us unfortunately.
    
    The code in this patch will enter A3SM sleep via the
    regular Suspend-to-RAM interface in the case of only
    wakeups supported by A3SM are enabled. If unsupported
    wakeups are enabled then Core Standby will be used
    instead.
